Just wondering, what versions of the software are you all using? Did you get the software from download.com?

As far as I know, any changes in any files or folders (moving, renaming, deleting, etc) causes the program to re-index pre-1.12, and in earlier versions also spawned a thread for every shared (sub)folder on yoru machine.

If you are using 1.12, did you somehow manage to get your /temp or /xolox directories shared? Are you sharing whole hard drives? Organizing your shared folders?

I really don't know what to tel you if none of those are true...
